Final answer:
Performing a Ripple Trim can unintentionally alter the timeline, causing desynchronization between audio and video and misaligning other elements.
Step-by-step explanation:
The danger of performing a Ripple Trim in video editing is that it can unintentionally alter the timing of footage or other elements later in the timeline. A Ripple Trim is a type of edit that not only trims footage but also shifts all subsequent clips to fill the gap.
This can be useful for removing unwanted sections without leaving a blank space in the timeline. However, if the editor is not careful, doing a Ripple Trim could disrupt the synchronization of the video and audio, or it could cause other elements, like graphics or cutaways, to become misaligned with their intended timing.
